Turkey's state-run Anadolu Agency has reportedly obtained detailed information about Aug. 21 chemical attacks in Syria that killed hundreds, including the list of army forces that took part in the attacks.

The chemical attacks was allegedly conducted by Syrian regime forces simultaneously from two centers on Aug. 21 at around 2.45 a.m. and targeted residential areas and some zones between Duma-Harasta and Zamalka in East and West Ghouta.

The 155th Missile Brigade, including the 51st, 52nd, 577th, 578th, 579th and 1097th missile troops, as well as a technical support team, were allegedly involved in the attacks, the agency said.

Some 15 to 20 missiles with chemical warheads were fired by the 155th Missile Brigade in Kufeyte and forces from the 4th Armored Division on Qasyoun Mountain.

FROG-7/Luna and/or M600 missiles were fired from Kufeyte, while rockets with a 15-to-70-kilometer range were fired from Qasyoun.

Anadolu did not explain where it obtained the information from. Many countries, including Turkey, have blamed the Syrian government for the attack, but there has not yet been any definitive evidence showing which side was responsible for the deadly raid.
